Polyhedron in which all the faces are regular polygons, but not all are congruent.
There are 13 semi-regular polyhedra.
Example
- This is a truncated tetrahedron with a vertex arrangement of (3, 6, 6].
This code indicates that at each vertex, there is one triangle (3) and two hexagons (6):
- This is a truncated cube with a vertex arrangement of (3, 8, 8):
- This is a truncated octahedron with a vertex arrangement of (4, 6, 6):
- Ten other semi-regular polyhedra and their vertex arrangements are listed below:
- Cuboctahedron: (3, 4, 3, 4)
- Truncated cuboctahedron: (4, 6, 8)
- Rhombicuboctahedron: (3, 4, 4, 4)
- Snub cuboctahedron: (3, 3, 3, 3, 4)
- Truncated dodecahedron : (3, 10, 10)
- Truncated icosahedron : (5, 6, 6)
- Icosidodecahedron: (3, 5, 3, 5)
- Truncated Icosidodecahedron: (4, 6, 10)
- Rhombicosidodecahedron: (3, 4, 5, 4)
- Snub icosidodecahedron: (3, 3, 3, 3, 5)
